Abstract
The sandwiches of magnetic/nonmagnetic/magnetic (M/NM/M) materials have been investigated combined with Ruderman–Kittel–Kasuya–Yosida (RKKY) exchange interactions with mixed apins-2 and 3/2 using Ising model using Monte Carlo simulations. The RKKY value is obtained for different distance between the different magnetic and non magnetic multilayer. The RKKY exchange interactions as a function of distance between the magnetic multilayer have been given. The magnetizations and magnetic susceptibilities of each magnetic bloc are obtained. The reduced critical temperatures of each bloc and the system are obtained. The reduced critical temperature is obtained for a fixed size. The theoretical calculations showed an oscillating behavior of the magnetic parameters with increasing the nonmagnetic layers. The total magnetization versus the exchange interactions and crystal field in each bloc is established. The magnetic hysteresis cycles are established for a fixed magnetic parameters.
